Pallenis

Pallenis is a genus of flowering plants in the family Asteraceae, commonly known as the daisy family. The genus was described by Swedish botanist Carl Linnaeus in 1753. Plants in the genus Pallenis are native to the Mediterranean region, extending eastward into parts of Asia. They are typically found in arid or semi-arid environments, often on rocky slopes or disturbed ground.

Species within Pallenis are generally herbaceous perennials or subshrubs. They are characterized by their daisy-like flower heads, which usually have yellow ray florets and a central disk of tubular florets. The leaves are typically simple and arranged alternately along the stem. Some species may have a somewhat woolly or hairy texture.

One well-known species is Pallenis maritima, also known as Mediterranean sea holly or sea starwort. This plant is often found growing in coastal areas and is recognized for its resilience to salt spray. The flowers of Pallenis maritima are a bright yellow and are attractive to pollinators. Another species, Pallenis spinosa, is sometimes referred to as spiny pallenis due to its spiny bracts.

The genus Pallenis is of botanical interest for its adaptation to challenging Mediterranean climates. While not widely cultivated, some species are used in traditional medicine in certain regions. The ecological role of Pallenis plants includes providing habitat and food for local fauna. Research continues to explore the genetic diversity and ecological relationships of these plants within their native ecosystems.
